Never Ignore These 3 Furnace Smells

by Don Rackler on

furnace smells, San Antonio, TexasMany seasonal smells bring back memories of holidays past and enjoyable traditions. There are certain furnace smells, however, that are anything but pleasant, and almost certainly lead to a safety hazard.

If you ignore these three furnace smells, you could be putting you and your family at risk:

Musty smells

By the time you smell a musty odor, it’s likely that mold or mildew has been forming for awhile. It’s particularly problematic when a musty odor emanates from the heating ducts, as the origination of the mold or mildew may be the furnace system, the cooling system or the ductwork. You may need to have the system cleaned by a professional, or the ductwork replaced.

Electrical odors

If certain components within the furnace are wearing out or over-stressed, you may notice an overheated electrical smell. The electrical wires and motors within the furnace help to move air through the system and aid in combustion and, as these parts or wires wear out, you may smell burning wires or rubber.

Burning smells

A few different scenarios cause a burning dust smell to be released from the furnace. After sitting idle over the long summer months, dust builds up inside the combustion chamber of the furnace. When you fire up the furnace for the first few times, that dust gets burnt off, which results in the burnt dust odor, and it may even release some smoke, too. If you start up the furnace without installing a new filter, you’ll run the furnace with a dirty, full filter, which could compound the situation. When a new furnace is installed, it will burn off some of the oil applied to the internal components to prevent rusting, releasing a burning odor.
